A convicted sex offender from San Bernardino who was found guilty in April of molesting two sisters — one of them for more than a decade — was sentenced today to 800 years to life in state prison.

David Louis Fields, 62, was sentenced in San Bernardino Superior Court on 16 felony counts of lewd and lascivious acts with a child, according to Deputy District Attorney Bobbie Mann. A jury found Fields guilty of all counts on Apr. 13.

Mann said she was pleased with the outcome the case, which was filed in June 2006.

“I think it brings closure for everybody,” said Mann.

Redlands police arrested Fields on June 26, 2006 at his Fairfax Drive apartment, in San Bernardino, after being alerted by police officers in Colton, who were investigating incidents of molestation regarding Fields, according to a Redlands press release.

One of the victims, who was 16 years old in 2006, first reported being molested to authorities in Las Vegas, who in turn alerted Colton police. The victim said the molestation began when she was 5 years old and lasted until 2003, when she was 13 or 14 years old and living in Redlands.

After reporting the abuse, the victim contacted her older sister, who was 21 in 2006 and lived in Colton. The older sister reported to Colton police that she was also abused by Fields starting when she was 7 until she was 14.

Investigators say the girls were also molested in San Bernardino, Highland and Rialto in addition to Redlands and Colton.

Fields has a prior conviction for committing a lewd act upon a child under 14 in June 1977 in Los Angeles County, according to San Bernardino Superior Court records. He also pleaded guilty to a felony count of failing to register as a sex offender in April 2004.

Fields, who is also known as David Louis Nance, is a registered sex offender on the state Megan’s Law web site.
